XSENS XACT
Clamp-On Water Cut Meter
The XACT Water Cut Meter provides accurate and reliable 0–100% water cut measurement using a fully non-intrusive clamp-on design. Mounted on the outside of the pipe, it measures the percentage of water-in-oil (WIO) via ultrasonic Speed of Sound (SoS) technology, eliminating the need for intrusive sensors, mixers, or pipe modification.
Developed with Christian Michelsen Research (CMR) and NORCE, the XACT meter achieves ±1% absolute accuracy across the full water cut range. With no contact with process fluids, it avoids erosion, corrosion, scaling, or waxing, ensuring robust long-term performance.

- Clamp-on ultrasonic transducers – no pipe penetration
- Measures 0–100% Water Liquid Ratio (WLR) with ±1% accuracy
- Installation time: 2–3 hours, even near bends and valves
- Integrated flow computer with 4–20 mA / Modbus outputs
- Immune to pressure, viscosity, or sour service conditions
- No need for static mixers or straighteners
- Remote connectivity via WiFi, cellular, or satellite; solar power options
- Ex Zone 1 & 2 certified (ATEX, IECEx), non-certified versions also available
